BALING-PRESS.

SPECIFICATION forming part of Letters Patent No. 394,623, dated December` 18, 1888.

Application filed July 24, 1888.

To aZZ whom it 71mg/ concern:

Be it known that I, EPHRAIM C. SOOY, a citizen of the llnited States, residing at Kansas City, in the county of Jackson and State of Missouri, have invented certain new and useful Improvements in Baling-Presses; and I do hereby declare that the following is a full, clear, and exact description of the same, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, forming a part of this specification.

My invention has for its obj ect primarily to enable the initial velocity of the pitman in a horse-power press in the line of its work to be augmented by means of and within the radius of the crank prior to the application of the stroke of the crank upon the pitman to effect a compression of the material, thereby accomplishingin a short portion of a circuit described by the draft-pole a reciprocal movement of the pitman so far in the direction of the feed-receptacle as the loose material in the press will permit.

The invention consists in the novel construct-ion and combination of parts, which will Iirst be fully described, and specifically pointed out in the claims.

In the drawings, Figure l is a side elevation of a movable baling-press, showing my improved horse-power mechanism; also, a p ortion of the feed-receptacle and the plunger thereon. Fig. 2 is a det-ail side elevation of the horse-power mechanism with the feed-receptacle removed. Fig. 3 is a plan view of the horse-power mechanism, as seen in Fig. 2, showing the pitman retracted and the end extending beyond and in a parallel relation with the cranks on the shaft and in a position at the beginning of a stroke. Fig. 4 is a plan view in detail of the bed of the press with the yoke, upper portion of shaft-bearings, and shaft removed, showin the pitman, the guide and supporting rollers, and the end of the crank bearing upon the end of the pitman at the middle of the stroke. Fig. 5 is a plan view similar to that seen in Fig. et, showing the position of the crank and pitlnan at the dead-center or end of the stroke. Fig. 6 represents a longitudinal sectional view of the bed of the press, the cylinder thereon, and

the pitman, showing the arms on the pitman for operating the piston in the cylinders.

In the construction of my improved horsepower mechanism and press, A represents a horizontal platform or bed, which is made narrow in width and of the desired length to support the power-shaft and feed-receptacle. Upon the extreme forward end, a, of the bed A is placed the U-shaped bearing or casting for the crank-shaft, which consists, first, of ahorizontal plate, b, which extends from the extreme end, a, of the bed A a proper distance to afford the bearing for the crank-shaft toward the opposite end of the bed. From the plate b, a short distance from the extreme end, a, of the bed A, to admit the transverse axle-bearings supporting the bed and also the crank-shaft, is extended in an upward inclined direction a support, h', 'one portion, b2, of which is bent in a horizontal relation at the upper end and extends in one direction to a point in a vertical relation above the eX,- treme end of the portion a of the bed A, and in an opposite direction a portion, B, extends a suitable distance for the reception of the crank and shaft, and upon the extreme end of said portion B is placed a journal-box, B', the cylindrical opening in which is in a vertical relation to the bed.

Directly beneath the journal-box B', in a vertical line with its opening, and in the plate h, is made a cylindrical bearing, b3. In the journal-box B is then placed a vertical shaft, C, the lower end, c, of which rests in the bearing b3 in the plate b. Upon the shaft l, and extending radially in one direction and from directly opposite sides of said shaft, at a point on said shaft intermediate the journalbearings B b3, are the cranks (1 C2. In a transverse relation, and through the extreme ends of the cranks C C2, are made the slots c c2, and in said slots, between the portions c5 c* of the ends of the cranks C C2, are placed in a vertical relation the anti-friction rollers c3 c4, which rotate on the pivots cx CX, which pivots extend in a vertical relation through said portion c5 c6. The upper end of the shaft (l extends through and a slight distance above the shaft-bearing 8', and upon said upper end of said shaft is rigidly attached in a transverse relation ayokc, I), the

ICO

edge 7l and at an obtuse angle.

which receptacle is placed a reciprocating plunger, II. Forthe purpose of obtaining the initial speed of the plunger, a pitrnan, I, is made of the proper length, one end of which is pivotally connected to said plunger I-I, vand the opposite ,end extended in the direction of the cranks C C2 so far as to perreceptacle G necessary for compressing the material and the operation of the cranks, constructed as hereinafter described.

To support the end of the pitman I in the direction of the cranks C C2 in a horizontal relation, Vtwo vertical supports, la 7c, are atthe upper portion of the bed A, a short distance from the path of the ends ofthe lcranks C C2,` and,in the direction toward the receptacle G. To the upper ends of the supports k la is pivotally attached the respective opposite ends k k2 of thehorizontal anti-friction roller K, upon .which the pitman I reciproeates. The end of the pitnian, which reciprocates past the crank-shaft C, conforms in shape to the human foot, the toe portion extending in an outward direction in its relation to the shaft C, and more particularly'T is constructed as follows:

The pitman I consists of a longitudinal bar of equal thickness in a vertical' relation, and to wit-hin a proper distance of the end which reciprocates past the shaft C is of a uniform width. y The inner longitudinal edge portion, t', which plays near shaft C, extends in one direct'line from its pivotal point on the plunger II to within a short distance of its extreme opposite end, at which point, for a distance nearly one-half the circumference of the roller c4 in the crank c2, a portion of said end along the edge is cut away in a curved relation, as at fi. Upon the extreme end, and in the longitudinal direction of the -pitman I, is made a slight curved depression,z'2`, of a proper size to receive a portion of the periphery of rollers c3 ci.

From a line vdrawn in the horizontal direction of the `pitman I, between opposite parallel edges and intersecting the depressed line of groove fr?, the end fix of the pitman is extended a short distance beyond the said de pressed portion 2 outwardly in` relation to shaft C and in an opposite direction to the From the depressed portionz' ofthe end of the pitman the incline is slightly ascending, and to the extreme or toe end of the pitman a short outf ward curve, zi", is given to said end of the pitman. Around the toe end of the pitman the curve is made gradual, and at i4 a return inward curve is made, the portion removed from the pitman to form said curve contracting the widtlrof the pitman in width at point :c x on said pitman, which is slightly in rear of the curved portion vl on the edge From the contracted portion at the point to the point g/ on the outer edge of the pitman I is described an incline plane, fi, tothe outer edge, 1f, the 4Width of the pitman increasing in the direction of its opposite pivotal end and toward said point y, said point yy being the widest part of the pitinan, and extends a suitl able distance from the point .r to enable the pitman to be checked in its rebound, as heremit the full extension of the plunger in the inafter described. For the purpose of obtaining a lateral bearing ,for the vibrating end of the pitman, two longitudinal arms, L L', are first made of the The cranks C C2 are first turned to a position in the longitudinal direc. tion of the bed A and the vibrating end of the tached in a transverse relation to and upon required length.

pitman I retracted as far as necessary past the crank C upon the side of the bed of Vthe press, which permits the longitudinal edge i of the pitman to nearly approach the shaft C.

. One end portion of the arm L is then attached rigidly to the under-side portion of the support B in the following manner: Projecting' laterally from the side of the support B, in a line horizontal with the under portion of the box B and on opposite'sides of said support, are castth'e .flanges bl. In rear of said box B of the support 13,011 the side of the bed of the press opposite to that occupied by the pitman I and to said flange b4, is attached rigidly, by

the bolt Z in a horizontal relation, one end ofthe arm L. The said arm L is then extended to a point beyond the radius of the cranks C C2 and past the pitman I and in the direction of the point y of the incline portion of the said pitm'an, the said arm describing nearly an obtuse angle to the longitudinal plane of bed A. v

Upon the bed A, directly beneath the arm L, is attached rigidly to the plate Z9, bymeansv of the bolts l Z, a similar arm, L', which arm L extends in a horizontal relation at the sameV angle as arm L in its relation to bed A, and its extreme end to a point past the pitlnan I in a vertical line with the extreme outer end. 1of said arm L.

Through said arms L L are made in a Vertical relation the perforations Z2 i2, in which perforations is fitted a pivot, Z3, and upon said pivot is placed in a vertical relation an anti-friction roller, M,

vwhich bears upon the incline plane of the outer edge of the pitinan I. A lug,vN, is attached rigidly to the bed A of the press at a'V vpoint on the side of the supporting-roller -K toward the feed-receptacle and ata point intermediate the opposite longitudinal sides of the bed A of the press, which willA prevent Athe pitman from approaching quite to the TOO IIO

dead-center, which lug extends in a vertical relation above the horizontal plane of the pitman I.

For the purpose of checking the rebound of the pitman I between the bearing or roller M and the longitudinal sides of the cranks C C2, the ends of which extend a slight distance outwardly on opposite sides of shaft C, at the point of connection with said shaft, a cylindrical opening, es, is made in said ends of cranks C C2, in a transverse relation to said cranks and diametrically in relation to shaft C, and on relatively opposite sides of said shaft, in which openings are placed the rubber or wood cushions C7, which extend outwardly to a point slightly in advance of aline drawn tangentially from the periphery of roller c3 to the periphery of roller c4. For the purpose of affording additional means for preventing the rebound of the pitman, and the distance of recoil of the vibrating end in its relation to and past roller M, between the points 1/ on said pitman, an air-cushion or hollow cylinder, S, is rigidly attached to the upper side of the bed A of the press, extending in the longitudinal direction of and beneath said pitman, and in position is placed so far toward the shaft C as to be removed from the path of plunger H. The opposite ends of the air-cylinder S are closed with the ends s s, which are perforated in a central transverse relation and retain air under pressure of the piston. Within the cylinder S is a piston, s', and extending longitudinally through the cylinder S and the ends s s, an equal distance beyond said ends and connected rigidly with the piston s', is a pistonrod, s2. lo the under side portion of the pitman I and at a point close to the end of the cylinder S, toward the receptacle G, the plunger H, beingI retracted the desired distance from the said receptacle, is rigidly attached in a transverse relation to said pitman a depending arm, rf, which extends so far in a downward relation as to contact with the end of the piston-rod Upon the pitman I, and in the direction of its vibrating end, is rigidly attached asimilar depending arm, 7, which extends downwardly and contacts with the end of the piston-rods?, which is extended in the direction of the shaft C, nearly to its full length, so that as the plunger Il is reciprocated within the receptacle (i thearms i [7 play alternately on the opposite respective ends of the piston-rod s2. The air on opposite sides of the piston s, in either direction in which the piston is moved, compresses the air toward the ends, which slowly escapes around the piston-rod and the rebound of the pitman is gradually restrained.

One portion of the press carrying the power is shown attached to the axle o, which extends in a transverse relation between the portion a of the bed A and the portion b2 of the horizontal support for shaft C, which axle is provided with the wheels I. At a point on axle o, between the traction-wheels P P, is attached rigidly a post, R, which extends in a vertical relation a sufficient distance to permit the end b4 of the support B to rest thereon and bring the plate l) 011 bed A nearly against the under side of the axle O. A short extension of the post R, beneath the axle O, is perforated in a vertical relation, and receives a stud, yr, on the plate b, and through the portion b4, in a vertical relation, is inserted a bolt, fr', which enters a perforation, r2, in the upper end of the post R, which enables the axle to be turned at an angle to the bed A. The opposite end of the press vis shown unsupported, which portion may be mounted in any manner preferred.

In the operation of the press thc vibrating end of pitman I is first retracted in the longitudinal direction of the end portion, (i, of the press, as seen in Figs. l, 2, and 2l. The piston s', as seen in Fig. l, being near the bottom s of the cylinder S, the material to be baled is first placed in receptacle G, and power is then applied and the yoke l') and shaft C rotated in the direction of the arrows or relatively to the right. The anti-'friction roller c4 on the end of the crank C2 is then brought to bear against the inner edge, i, of the vibrating end portion of pitman I. The opposite inclined portieri zi', near the point y, is thrown against anti-friction roller M (see dotted lilies in Fig. 3,) and as the leverage oi' crank C2 is increased the tendency of crank C2 to turn upon its axis past stationary antifriction roller M in the radius of driving-shaft C operates to eject the said vibrating end of pitman and the pitman l is thrown in the direction of the receptacle G, the portion of the vibrating end from thc point -1/ to the point ,1' on the inclined plane c being moved at an accelerated speed, and the plunger ll forced within the receptacle (i to a position in contact with the material to be compressed, and during which movement of the pitman the crank c2 follows the incline 1", and in one quarter of its circle of rotation the roller c is in a position nearly at right angles to the pitman I and in the depression [2, in readiness to impart thc stroke which compresses the material in the receptacle G, the t'oot portion of the pitman being meanwhile released from contact with roller M. Thus it may be seen that a crank may be employed comparatively short in length to effect the result described. Upon another quarter rotation of the crank C the said crank and pitman are nearly at a dead-center, as seen in Fig. The pitman I, held by the lng N from a direct dead-center, throws the plunger II within the receptacle G and compresses the material. As soon as the compression is effected, the rotation of shaft C is past the curved portion L" of the pitman, the material under compression expands, and the plunger H and the pitman rebound instantly to a position, as seen in Fig. 3, the vibrating end of said pitman is thrown between the roller M and the shaft C to a position parallel with cranks C C2, the edge L' IOO of the pitman contacting with the cushion c7, and the recoil checked when the highest point of the incline i4 meets `the roller M. In the rebound of the plunger the arm i .meets the end of piston-rod s2, and the piston slowly yielding as the air escapes serves to lessen additionally' the violence of the recoil. The

crank C is then operatedl to move the pitman,

and the compression of the material repeated in a corresponding manner.

It will readily be seen that the rebound of the pitman is readily checked in a light power-press between the roller M and the cushion c7, and the service of the air-cushion is only employed as occasion requires.

Having fully described my invention, what I now claim 4as new, and desire to secure by Letters Patent, is-
